The possibilities to build a house may be limited due to restrictions of both the available surface, as well as regulatory and economic constraints. The diversity of the projects presented typologies reflect the possibilities that can be developed to achieve this goal. And although they can vary in climate and topography where they are, they all share a common theme: housing design with a tight budget.Whether full or partially prefabricated houses, extensions, houses built with container or even a studio or a foster home for children.
